Power limited is stock which is 100%, should i increase power limited,does it matter when the limited is only 103%? (max is 103% which just now surpriced me, when i tried to set it's limited, that it isn't higher)

Doing boarderlands 2 (2560x1080) with stock fan profile and all maxed out it got up to 79 degresse celsius wich is for me okay, it shouldn't throttle and if i increase power limited i want it still to be under 80 degresse doing games

when is the power limited of only 103% a problem for overclocking this card, as you can see in the link 1020 mhz on the core and 1765 mhz for the ram is the limited

You should only need to increase the power limit if during a gaming session you check the monitoring software and it shows the Power Percentage getting higher than what you have it set as, thus throttling the clock.

You can also set the temperature as priority so that power limit won't matter as much.

As MxPhenom 216 posted check with GPU-Z or MSI AB the power usage% while gaming and note the max it hit .

If it is below your slider amount your fine .
It will downclock if it hits limit .
Needing more power comes with higher clocks and voltages , also your game settings and res .
I would recommend using MSI AB and setting the OSD to display power% ,clocks and GPU temps at very least .
